 === Background ===
 
+[http://cairographics.org/ Cairo] is a 2D graphics library with support for multiple output devices, including PostScript, PDF, and SVG file output and also direct display rendering under various operating systems.
+
+[http://lemon.cs.elte.hu/pub/doc/1.1.2/a00134.html GraphToEps], LEMON's current graph visualizing tool creates an Encapsulated Postscript file by hand. Implementing a similar tool based on [http://cairographics.org/ Cairo] would provide various output formats and easy integration to graphical user interfaces.
+
 === The Task ===
+
+Develop a tool that provide similar functionality to [http://lemon.cs.elte.hu/pub/doc/1.1.2/a00134.html GraphToEps] but uses the [http://cairographics.org/ Cairo] library for drawing. In order to achieve further flexibility the following changes should be made compared to [http://lemon.cs.elte.hu/pub/doc/1.1.2/a00134.html GraphToEps].
+ - The extensive use of named template parameters should be replaces by a mechanism using virtual function calls. (In fact, this will make the code much easier).
+ - The necessary preprocessing of the graph should be separated to the actual drawing, in order to speed up this latter process.
